The bag I wrote about a few weeks ago from Bluefly definitely looked authentic -- it arrived with a torn security tag and looked like it had a minute flaw in the leather/retouching -- I called them, sent it back, they refunded everything tho it took another call to get the shipping refunded too. Probably as it was my first purchase ever with them. They were very nice about it all.
I'd shop with them again just be careful to really check out the bag once you get it.
